Profman: Skip dex file verification for boot jars

The introduction of new access flags into boot jars causes them to
fail dex file verification. The files are verified in `hiddenapi`
and verification should be skipped in subsequent attempts to open
them. This patch adds a new flag '--skip-apk-verification' which
instructs `profman` to skip dex file verification.
